Yes I do; it's the only way I can get the server to send anything.

I have taken it offline.

I've already made your suggested change, and when doing that it only will relay
mail sent to other people with email addresses @cityairlines.net (our domain).

I'm not using the split config. I'm using the configuration files that were
installed by debian. As mentioned in an earlier post in this thread by Adam D.
Barrat, when I first installed exim4 using apt-get, I encountered the following
prompt, to which I accepted the default, which is to relay for no one. Even
having done so the config file created by the installation said "domainlist
relay_to_domains = *"
prompt was:
------------------------------------------------------------------------ | Please enter here the domains for which you accept to relay the mail. | | Such domains are domains for which you are prepared to accept mail
| from anywhere on the Internet. Do not mention local domains here. | | The domains you enter here should be separated by colons. Wildcards
| may be used. ------------------------------------------------------------------------
As I stated, I left the prompt empty.

This I have done, and my server continues to function as an open relay. What
the #@$(* is going on?! I am going nuts. My boss is very unhappy that the smtp
server is still down.
I even tried using postfix today. Did no good. I couldn't get it to work
either. I experienced the same problems, and seeing this I decided that if I
couldn't get anything to work, I might as well stick with exim4 as it is the
preferred MTA for Debian and as such I feel that it is probably the best choice.
